The 2nd clause of this explanation of the gerundive is not clear to me. I know it translates as something like: He by whom anything needs to be done is with the gerundive in the dative case. BUT I'm not clear about the role of 'significatur'.

I'm not quite sure what Iulius is saying here. There's no question mark at the end of this sentence though it feels like a question - Doesn't Quam ob rem = cur? Does 'ipse' refer to Iulius or his guests / others?

My best attempt at translation is: 'for what[ever?] whether I'm here or away I have [not?] found out anything by letter that happened recently in Rome. Can anyone explain?

I will ty to translate this: Because no Athenian had after human memory (in human memory) killed his own father, nor did the wisest man think that any such (quemquam) inhuman crime would take place (facturum esse).

I will try to translate this: But certainly it is one thing to kill one's father, it is a different (longe aliud) thing to execute a criminal servant, for the worst crime the severest punishment is just'

'id supplicum in servos statutum est.' Does this mean 'the punishment is appropriate for slaves'?

24) Quod venus suadet iniuria non est!

Nonne 'Quod' neutrum nominativus est?

25) Cornelius: "Tacendum est, non bibendum!"....

Orberg says this indicates what is desirable / should be done generally (in this case). 'There sould be silence, not drinking...' Are these gerundives in Neuter Nominative... (id) tacendum est...etc..?

Re 23.Lewis and short give: stature - to decree: ...With acc. (post-Aug.): remedium statuere, to prescribe a remedy against public abuses, Tac. A. 3, 28; 6, 4: Caesar ducentesimam (vectigalis) in posterum statuit, decreed that one half of one per cent. be the tax,

Certainly an injustice should not be done to a slave, but it is necessary to punish dishonest or runaway slaves severely, nor therefore is any but severe punishment of servants of that type able to deter them from crime and so keep them at their work.
